Description

Technical Field

[0001] This utility model relates to the field of coupling technology, specifically to a coupling capable of reversing transmission. Background Technology

[0002] A coupling is a device that connects two different rotating bodies, primarily used to transmit torque and motion, while also compensating for misalignment between the two shafts. It reduces the difficulty of assembly and adjustment by absorbing axial misalignment between the rotating bodies, and in the event of unexpected overload, it is the first to fail, thus protecting other equipment.

[0003] For example, a coupling according to Chinese patent application CN202321584015.8 includes: a base body having a first receiving groove and a second receiving groove, the first receiving groove communicating with the second receiving groove, the groove diameter of the first receiving groove being larger than the groove diameter of the second receiving groove; and a movable body, a first part of which is confined within the first receiving groove, and a second part of which is located within the second receiving groove; wherein, the side of the base body facing away from the second receiving groove is used for connection with an actuator, and the second part of the movable body is used for connection with a driven mechanism. In the case of concentricity deviation between the driving shaft and the driven shaft, the additional torque generated radially between the driving shaft and the driven shaft can be reduced, and the influence of machining tolerances between the driving shaft and the driven shaft can be reduced. Thus, in the axial direction, the driving effect of the driving shaft on the driven shaft is improved.

[0004] However, in actual use, the impact of the equipment during long-term operation can easily damage the inside of the coupling, which can lead to problems such as displacement error and slight axial, radial and angular offsets caused by foundation settlement, thus affecting actual use and reducing the effectiveness of use. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a reversible transmission coupling. By utilizing the elastic deformation capability of springs, it can effectively absorb and buffer impact loads, vibrations, and wave energy in the transmission system, significantly reducing the dynamic load transmitted to the connected equipment. At the same time, the flexibility of the springs can compensate for the misalignment between the two shafts, maintaining the continuity and smoothness of the transmission, thereby achieving advantages such as buffering and vibration reduction, misalignment compensation, and overload protection, effectively solving the problems in the background technology.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a coupling that can reverse transmission, comprising two sets of two vertically distributed half-coupling bodies, wherein fixing plates are fixedly provided on the front and rear side walls of the half-coupling bodies;

[0007] There is a buffer assembly between each pair of half-coupling bodies to reduce the impact during rotation;

[0008] A redirection assembly is provided between the two sets of two half-coupling bodies for redirectable rotation;

[0009] The buffer assembly includes four buffer connecting rods. Each set of two half-coupling bodies has two slots distributed front and back on one side wall. One end of the buffer connecting rod passes through the slot and is provided with a fixing thread. The buffer connecting rod is located inside the half-coupling body, and a nut is connected to the other end of the buffer connecting rod by the thread. A spring is sleeved on the other end of the buffer connecting rod.

[0010] Preferably, the redirection assembly includes two gear rings, the other end of the buffer connecting rod is fixedly disposed on one side of the gear ring, and both ends of the spring are respectively fixedly disposed between one side wall inside the half-coupling body and one side of the gear ring, which facilitates long-term operation and allows the spring to absorb the impact force between the half-coupling body and the gear ring, thereby effectively reducing wear.

[0011] Preferably, the other side of the half-coupling body is provided with a number of evenly distributed tooth grooves, and a number of evenly distributed tooth blocks are fixed on the tooth ring, with the number of tooth blocks corresponding to the number of tooth grooves. The tooth blocks are engaged inside the tooth grooves, and a bearing sleeve is connected between the two tooth rings by a bearing, so as to allow the two tooth rings with their inner and outer rings to rotate freely.

[0012] Preferably, the top and bottom of the outer wall of the gear ring are provided with two threaded holes distributed front and back, and the two threaded holes are connected to the same fixing plate by two bolts, which makes it easy to unscrew the bolts and disassemble the fixing plate.

[0013] Preferably, the same U-shaped support rod is fixed between the two fixed plates on the same side, which makes it easy to fix or remove the two fixed plates at the same time.

[0014] Preferably, the two fixing plates on the same side are connected by the same fixing bolt through a thread, which is used to fix the two half-coupling bodies in a set, so as to facilitate the fixing of this utility model on the shaft of different equipment.

[0015] Compared with the prior art, this utility model provides a coupling that can redirect transmission, which has the following beneficial effects:

[0016] 1. This utility model connects the toothed blocks on the gear ring with the corresponding toothed grooves on the half-coupling body, and the four buffer connecting rods on the gear ring pass through the slots on the half-coupling body. Then, the nuts are screwed into one end of the buffer connecting rods to fix the half-coupling body and the gear ring. During operation, the elastic deformation capacity of the spring can effectively absorb and buffer the impact load, vibration and wave energy in the transmission system, significantly reducing the dynamic load transmitted to the connecting equipment. At the same time, the flexibility of the spring can compensate for the slight axial, radial and angular offsets between the two shafts caused by installation errors, thermal expansion or foundation settlement, maintaining the continuity and stability of the transmission, thereby achieving advantages such as buffering and vibration reduction, deviation compensation and overload protection.

[0017] 2. This utility model achieves simultaneous rotation of the shafts at both ends by fixing two fixed discs and U-shaped support rods to the top of two gear rings respectively, and fixing the position between the two gear rings by screwing bolts into the threaded holes. Then, by unscrewing the bolts and removing the fixed discs and U-shaped support rods from the two gear rings, the two gear rings can be connected only by bearing sleeves, allowing both ends to rotate freely and transmit power in two different directions. The bearing sleeves ensure smooth transmission and low friction even after angle adjustment. Therefore, it is not necessary to replace the entire utility model or make complex modifications to the equipment base. The direction of the two connecting shafts can be flexibly adjusted according to the actual installation space, equipment layout changes, or debugging needs, which greatly improves the adaptability of equipment installation and compatibility with complex spatial layouts.

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] like Figure 1-4 As shown, this utility model provides a coupling with reversible transmission, including two sets of two vertically distributed half-coupling bodies 1. The front and rear side walls of the half-coupling bodies 1 are fixed with fixing plates 3. The two fixing plates 3 on the same side are connected by the same fixing bolt 4 through threads, which is used to fix the two half-coupling bodies 1 in one set, so that this utility model can be fixed on the shaft of different equipment.

[0026] like Figure 1 , 2 As shown in Figure 4, a buffer assembly 6 is provided between each pair of half-coupling bodies 1 to reduce the impact during rotation. The buffer assembly 6 includes four buffer connecting rods 61. Two slots are provided on one side wall of each pair of half-coupling bodies 1. One end of the buffer connecting rod 61 passes through the slot and is provided with a fixing thread. The buffer connecting rod 61 is located inside the half-coupling body 1, and the end of the buffer connecting rod 61 is connected to a nut 63 by a thread. The other end of the buffer connecting rod 61 is fitted with a spring 62.

[0027] like Figure 1-3 As shown, a redirection assembly 5 is provided between the two sets of two half-coupling bodies 1 for redirection rotation. The redirection assembly 5 includes two gear rings 51. The other end of the buffer connecting rod 61 is fixedly disposed on one side of the gear ring 51. The two ends of the spring 62 are respectively fixed between one side wall inside the half-coupling body 1 and one side of the gear ring 51, which facilitates long-term operation and allows the spring 62 to absorb the impact force between the half-coupling body 1 and the gear ring 51, effectively reducing wear.

[0028] By setting up the buffer assembly 6, two opposing half-coupling bodies 1 are snapped onto the two ends of the input shaft and the output shaft, and fixed by the fixing bolts 4 on the fixing plate 3. Then, the tooth blocks 52 on the gear ring 51 are inserted into the corresponding tooth grooves 2 on the half-coupling body 1, and the four buffer connecting rods 61 on the gear ring 51 pass through the slots on the half-coupling body 1. Then, the nut 63 is screwed into one end of the buffer connecting rod 61 to fix the half-coupling body 1 and the gear ring 51. Subsequently, during the operation, the elastic deformation capacity of the spring 62 can effectively absorb and buffer the impact load, vibration and wave energy in the transmission system, significantly reducing the dynamic load transmitted to the connected equipment. At the same time, the flexibility of the spring 62 can compensate for the small axial, radial and angular offsets between the two shafts caused by installation errors, thermal expansion or foundation settlement, maintaining the continuity and stability of the transmission, thereby achieving the advantages of buffering and vibration reduction, compensation for deviation, and overload protection.

[0029] like Figure 1 As shown, the other side of the half-coupling body 1 is provided with several evenly distributed toothed grooves 2. Several evenly distributed toothed blocks 52 are fixed on the toothed ring 51, and the number of toothed blocks 52 corresponds to the number of toothed grooves 2. The toothed blocks 52 are engaged inside the toothed grooves 2. The two toothed rings 51 are connected by a bearing sleeve 53 through a bearing, which allows the two toothed rings 51 with their inner and outer rings to rotate freely. The top and bottom of the outer wall of the toothed ring 51 are provided with two threaded holes 54 distributed front and back. The two threaded holes 54 are connected by two bolts 55 to the same fixing plate 56, which makes it easy to unscrew the bolts 55 and disassemble the fixing plate 56. The two fixing plates 56 on the same side are fixed with the same U-shaped support rod 57, which makes it easy to fix or disassemble the two fixing plates 56 at the same time.

[0030] By setting the redirection component 5, the two gear rings 51 are connected to the shafts at both ends through bearing sleeves 53. Then, the two fixed plates 56 drive the U-shaped support rods 57 to be fixed on the top of the two gear rings 51 respectively. The position between the two gear rings 51 is fixed by screwing bolts 55 into the threaded holes 54. This allows the shafts at both ends to rotate in the same direction. After unscrewing the bolts 55, the fixed plates 56 and U-shaped support rods 57 can be removed from the two gear rings 51. The two gear rings 51 can only be connected by bearing sleeves 53, which allows the two ends to rotate freely and transmit power in two different directions. The bearing sleeves 53 ensure that the transmission remains smooth and low-friction after the angle is adjusted. Therefore, it is not necessary to replace the entire utility model or make complex modifications to the equipment base. The redirection between the two connecting shafts can be flexibly adjusted according to the actual installation space, equipment layout changes, or debugging needs, which greatly improves the adaptability of equipment installation and compatibility with complex spatial layouts.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
